The linear fit shows that it should intersect the y-axis at -0.00219, but in the plot it intersects the y-axis at about 2.25. Why doesn't the plot intersect the y-axis at -0.00219 how do I get it to intersect the axis there?
If you double-click directly on the X axis, a dialog should appear that says "X Axis" at the top. The very first box should be "From" and you can set it to 0 in order to display the Y-axis intercept more directly.
